LATCH.

SPECIFICATION forming part of Letters Patent No. 360,4.66x dated April5, 1887.

Application filed May 24, i886. Serial No. 203,147.

(No model.)

in the county of Tompkins and State of New York, have invented certainnew and useful Improvements in Latches; and I do declare the followingto be a full, clear, and exact description of the invent-ion, such aswill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and tothe letters and figures of reference marked thereon, which form a partofthisspecitication, and in which- Figures l and 2 are perspective viewsof my latch as used on small doors. Figs. 3 and 4 are views inperspective of my invention as used on heavy doors. Fig. 5 is a View inperspective of my latch or catch as applied to drills, cultivators, &c.Fig. 6' shows a modification.

My invention has' relation to improvements in the construction oflatches, and the purpose of my invention is to construct alatch in whicha wheel is the principle feature, thereby reducing friction and causingthe latch Vto opervided at one end with a knob, C, and bifurcated at theother, the forked portion curving downward. In this fork there ispivoted the wheel B. The latch A is pivoted in an opening in the smalldoor O, the knob being on the outside.

` Located properly within the cupboard or case of any kind to which adoor may be attached is the catch or keeper D, which may be constructedas shown,or in any other form. When vthe door is shut, the wheel B dropsover the catch or keeper D,fastening the door securely. By exerting aslight downward pressure on the knob C the other end of the latch A iselevated until the wheel is clear of the catch or keeper, when the doorswings open.

It will be noticed that in my construction, when the wheel B isperforming` the functions of a latch, the point of contact on theperimeter of said wheel B is at a point never below the center thereof,thus holding the door securely closed until pressure is exerted on theknob.

Instead ofthe bifurcated latch A, (shown in Figs. l and 2,) the latch Emay loe used, especially in heavy doors. piece either of wood or metalhaving one end, F, bent upward, taking vthe place ofthe knob C, and theother end, H, curving downward. To. the end II is rigidly secured thepivot G, on which the wheel Bis mounted and turns easily. The latch E ispivoted in an opening in the door P, the bent portion F being outside.To the door-jamb there is secured in the proper location a catch orkeeper, which may consist simply of a flat staple. When the door shuts,the wheel B drops over the catch or keeper, thus keeping the doorclosed. The same may be opened by pressing downward on the latch at thepoint F.

My latch, as represented in Figs. l and 2, may be applied to slidingdoors, one door being mortised, so as to receive the latch A, theordinary shank and knobs taking the place of the pivot a, and the otherdoor being mortised, so asv to receive the Wheel B, allowing it to dropover a straight edge, keeping the doors securely closed when the two arebrought together. Turning the knob lifts the wheel, and the doors may beopened.

. Fig. 5 shows my construction as applied to This consists of a drills,cultivators, Src., in which capacity the latch issometimes called a dog,and is used to support the teeth of those machines when it is desirableto hold the same out of the ground. S is a roller,connected with theteeth of the machine by flexible connections in the usual manner, sothat by turning said roller these iiexible connections are wound uponthe roller and the teeth raised above the ground. This roller is alsoprovided with the metal catch or keeper M. N is a handle, by which theroller is turned. K represents the frame of the machine, to which ispvoted the latch L, of wood or metal, and similar in all respects to thelatch A, Figs. l and 2, with the exception of the forked ends, whichextend, in Fig. 5, beyond the wheel. The wheel B, instead of 2 Y 36o 46cbeing on the latch L, is sometimes attached to What is called the catchor keeper, as shown in Fig. 6. When it is desirable to raise the teeth,the handle N is pressed, turning the roller S until the Wheel B dropsover the catch or keeper M, when it will hold it in the positiondesired.

Having thus described claim as follows:

l. The combination of a latch and its keeper, one of said parts beingprovided with a roller and the other engaging said roller at the line ofits pivot orbetween that point and the inain my invention, I
